WASHING MACHINE.

Application filed December 3, 1920. Serial No. 428,020.

To all whom it may concern:

Be it known that I, CHARLns E. McCoy, citizen of the United States,residing at Logansport, in the county of Cass and State of 6 Indiana,have invented certain new and useful Improvements in Washing Machines,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to improvements in pounder type washing machinesand the principal object of the invention is to furnish a machine ofthis type which is of simple inexpensive construction, which will ep- 1crate efficiently to quickly clean clothes and which may beexpeditiously manufactured.

Another object of the invention is to provide a washing machine of thistype having a main body formed from a single piece of sheet metal, andto support this body on angle iron legs which form the joints betweenthe cut portions of the'body.

A further object of the invention is to furnish the one-piece body withintegral flanges at the upper edges of certain of its walls, whichflanges project outwardly and function to support the hinged lid of thebody,

Another object of the invention is to furnish an improved basketdesigned to be arranged in the body and to be resiliently supported sothat it may reciprocate vertically when the pounder operates. Thesprings which support the basket are connected to the basket by meanswhich will not tear or snag the clothes contained in the basket.

A still further object of the invention is to furnish an improvedpounder whichmay be manufactured from channel and angle iron and whichwill operate ,efliciently without liability of tearing the clothing.

A still further object is to provide novel operating means for thepounder which is supported above the machine lid by brackets .45 ofimproved construction.

Finally it may be stated that the primary object of the invention is toimprove the entire construction of pounder type washing machines and toeliminate defects which have been found in these machines in practicaluse. i

With the foregoing objects outlined, and with other objects in viewwhich will appear as the description proceeds the invention consists inthe novel features hereinafter described in detail, illustrated in theaccompanying drawings and more particularly pointed out in the appendedclaim.

Referring to the drawings Figure 1 is a perspective view of my improvedmachine.

Fig. 2 is a vertical longitudinal sectional view of the same.

Fig. 3 is a horizontal longitudinal sectional View taken on line 3+3 ofFig. 2.

Fig. 4 is a plan view of the blank from which the body portion of themachine is cut.

- Fig. 5 is a perspective view of the improved basket.

Fig. 6 is a detail showing the manner in which the coil springs areconnected to the bottom of the basket.

Fig. 7 is a perspective view of the pounder.

Fig. 8 is a side view of said poun-der; and

Fig. 9 is an end view of the same.

Fig. 10 is a plan view of the underside of the machine lid showing thereinforcement for said lid. r

Fig. 11 is a side view of one of the pounder operating mechanismsupporting brackets.

4 Fig. 12 is a plan view of the basket blank.

Fig. 18 is a perspective view of the crank shaft.

Fig. 14 is a perspective view of the pounder rod guiding bracket.

In the drawings, l'designates the body of the improved machine, which inthe present instance is formed from a single piece of suitable material,such as sheet metal and this blank includes a body portion 2 which formsthe bottom of the tank when the blank is folded, side wings 3 which formthe sides of the tank when the blank is folded, and wings 4 which formthe ends of the tank when the blank is folded.

All of the wings are bent upwardly at right angles to the body 2 inorder to form a rectangular tank and the corners of this tank aresecured by rivets or the like to angle iron legs 5, the latter servingto form the joints between the wings and to reinforce the tankconstruction. The upper edge of one end of the tank is folded or bent 1outwardly to provide an integral flange 6 and the upper edges of thesides are likewise bent voutwardly to form similar flanges 7.

It will be noted that the ends of the. flange 6 and one end at each of hfl nges 7 are 110 angularly cut in order to form a continuous flangeextending from the rear end of one side to the rear end of the otherside of th tank.

These machines are generally used in connection with a wringerand forthis reason I have arranged a bracket 8 at one end of the tank in orderto support the wrmger. The other end of the tank is'provided with aninclined bracket 9 which serves as a support for the hinged cover 10when said cover is in raised position. This bracket 9 is provided withahand hole 10* adapted to re ceive the operators fingers when he desiresto move the frame on its supporting casters. When the cover or lid is.closed the flanges 6 and 7 engage the edge portions of the lid andsupport the same. 7

Located within the tank is my improved basket 11 which is preferably ofrectangular shape in horizontal basket is preferably formed of a singlesheet of metal and includes imperforate side and end walls and aperforated bottom. The ends of the basket are provided with handles 12.The blank from which the basket is formed includes a perforated body 13,side flaps 14 and end flaps 15. The flaps are bent upwardly at rightangles to the body 13 and these upwardly bent flaps form the walls ofthe basket and are secured together by corner angle irons 15 which arepreferably rivetted to the walls.

The perforations in the body or bottom 13 may be stamped out when thebasket blank is cut and this will facilitate manufacture of the basket.

The perforated bottom is provided With a plurality of helical coiledsprings 16 and the larger or base portion of the-springs are designed torest on the bottom of the tank 1. These springs are preferably made ofbrass or other material non-corrodible under the action of water. Theupper portion or upper coil of each spring is secured to the bottom ofthe basket by means of U- bolts 17. Each of these U-bolts passes througha plurality of apertures in the bottom, engages a portion 18 of thebottom and the upper coil 19 of a spring, and a clamp plate 20 is placedon the legs of the U-bolts and is secured in position by means of nuts21. I preferably employ one of these U- bolts for each spring and as thefree ends of the springs are secured they will not project through thebasket and snag the clothes. 7 As the curved portion of each U- bolt isarranged in the bottom of the basket,

the clothes will not be torn by the bolts.

Itwill be noted that the hinged cover is provided with an internalreinforcement formed of side bars 22, end bars 23 andfa central crossrail 24, the latter being apertured to receive the pounder rod of themachlne. The upper surface of the cover or cross-section. The 7 lid isprovided with a substantially U- shaped main bracket 25 which isapertured at its central portion to permit reciprocation ofthe pounderoperating rod 26. The lid is also provided with two parallel brack ets27 which are formed from strips of sheet metal or molded from cast iron.Each strip is bent intermediate its ends to provide anupper loop 28 anddiverging legs 29, the intermediate portions of the latter being securedtogether in order to provide the loops 28. These loops function asbearings for a shaft 30 which is provided at one end with a flywheel 31having an operating handle 32. The other end of the shaft'is bent toform a crank 33 which has a shoulder 34 and a reduced portion 35, thelatter being apertured to receive the cotter pinor other fastening means36. A pitman 37 has one of its ends apertured to receive'the reducedportion of the crank, and the pounder rod is provided with a pluralityof apertures 38 designed to receive the angular end 39 of the pitman 37.It will be noted-that the depth of the stroke of the pounder rod may beadjusted by shifting theend 39 of the pitman to one or the other of theapertures 38.

From the foregoingit will be seen that rotation of the fiy-wheel andshaft 30 will cause the extension of the crank to revolve, and thisrotatable movement will impartvertical reciprocating movement to thepounder rod 26. g V

The pounder per se consists of a plurality of parallel arrangedchannel-shaped irons 40 the lower edges of which are curled as shown at41 so that they will n0t-tearor snag the clothing in the clothescontaining basket. A strip of wood or the like 40* is arranged in thechannel of each of the mem bers 40 and angle irons 42 are arranged abovesaid members 40 and are secured to the members 40 and'40 by means ofnuts and bolts 43. While nuts and-bolts are shown in the drawing it willbe understood that any other suitable fastening means may be employed. i

The lower end of the operating rod 26 passes through the central one ofthe members 40 and a nut 44 is threaded onthe lower end ofthe operatingrod 26 passes through the central one of the members 40 and a nut 44 isthreaded on the lower endof theopcrating rod and functions to retain thepounder in rigid connection with the rod.

When it is desired to use the machine,

the-basket maybe removed and the clothing placed therein; Then thebasket is replaced and the lidmay be swung downwardly, and

7 t e-di t. f om the sa e lVhile I have shown and described thepreferred embodiment of the invention, 1 am aware that various changesmay be made in the construction shown Without departing from the spiritof the invention as expressed in the following claim.

What I claim and desire to secure by Let ters-Patent is:

A Washing machine including a tank, a basket arranged Within said tankand having a perforated bottom, coiled springs arranged between thebottom of the tank and the bottom of the basket, and U-shaped boltshaving their curved portions arranged Within the bottom of the basket,the leg portions of said bolts extending through the bottom of thebasket and engaging the upper coil of the springs, clamp plates mountedon the legs and fastening means securing said clamp plates on said legs.

Tn testimony whereof I hereunto affix my signature.
